Lemmy is licensed under the AGPLv3. I don’t want to rely solely on my own legal interpretation of the license, so I’m wondering if anyone has any explicit knowledge on the matter.
As an aside, am I correct in assuming that, if someone does make changes to the source code, they must host, and link to it?
EDIT (2023-09-27T22:22Z): I am just now seeing that at the bottom of a Lemmy instance’s site, there is a link that says “Code”. It appears that this is handled automatically.
But if you modify the source code you’ll probably need to link that somewhere e.g. in the sidebar
I have found that instances that do seem to modify the source code just use the existing “Code” link and simply point it to their own repo instead.
